SMH-02B01 thermopile-type infrared array sensor module with 16 x 16 elements for temperature measurement and detection of human body and objects.

This module is equipped with a sensor IC and an Si-lens optical system, and features an MCU with built-in A/D converter that generates digital output via an synchronous SPI serial interface, of both converted emission temperature of each sensor element and ambient temperature. A 200 to 2000 variable gain preamplifier enables wide temperature range measurement up to 250°C using auto range control via software.

SMH-02B01 offers advantage of high output sensitivity and wide range of temperature detection. Operating temperature range is 0°C to 50°C
16x16 array example show higher resolution with wider 90° FOV:
